/n_TOF Collaboration
The$^{16}$ O(n, ${\alpha }$ )$^{13}$ C reaction, as the inverse reaction of the astrophysically important$^{13}$ C( ${\alpha }$ , n)$^{16}$ O reaction, is proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas has been developed and a prototype was constructed at Helmholtz-Zentrum Dresden-Rossendorf(HZDR), in Germany.

(HZDR, Dresden) ; Hartmann, A. (HZDR, Dresden) ; Hensel, T. (HZDR, Dresden ; Dresden, Tech. U.) ; Hoffmann, H.F. (HZDR, Dresden ; Dresden, Tech. U.) et al.
The dipole strength of the nuclide $^{76}$Ge was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.8 and 12.3 MeV at the $\gamma$ELBE facility. We identified 210 levels up to an excitation energy of 9.4 MeV and assigned spin $J$ = 1 to most of them. [...]

The dipole strength of the nuclide $^{66}$Zn was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.5 and 13.4 MeV at the γELBE facility as well as using quasimonoenergetic and linearly polarized photon beams of 30 energies within the range of 4.3 to 9.9 MeV at the HIγS facility. A total of 128 J=1 states were identified, among them 9 with 1$^+$ and 86 with 1$^−$ assignments. [...]

The spent fuel of current nuclear reactors contains fissile plutonium isotopes that can be combined with uranium to make mixed oxide (MOX) fuel. In this way the Pu from spent fuel is used in a new reactor cycle, contributing to the long-term sustainability of nuclear energy. [...]
